vue 引入fastclick插件 ios键盘无法调起或者反应慢

 var length; // Issue #160: on iOS 7, some input elements (e.g. date datetime month) throw a vague TypeError on setSelectionRange. These elements don't have an integer value for the selectionStart and selectionEnd properties, but unfortunately that can't be used for detection because accessing the properties also throws a TypeError. Just check the type instead. Filed as Apple bug #15122724.

 if (deviceIsIOS && targetElement.setSelectionRange && targetElement.type.indexOf('date') !== 0 && targetElement.type !== 'time' && targetElement.type !== 'month') {

 length = targetElement.value.length;

 targetElement.focus();

 targetElement.setSelectionRange(length, length); 

 } else {

 targetElement.focus(); 

 } 

};
